Stata program files:

(1) tables1&2_sum.do -- produces summary statistics in Tables 1 and 2

(2) table3_main_op.do -- estimates bivariate order probit models; produces results in Table 3

(3) table4_freqs.do -- produces predicted probabilities used to construct estimates in Tables 4 and 5

(4) table6_genl.do -- estimates generalized bivariate ordered probit with four possible state dependence parameters;
produces results in Table 6

(5) table7_false.do -- falsification test for biv ordered probit models; produces results in Table 7

(6) table9_excl.do -- estimates biv. ordered probit models with alternative exclusion restrictions; produces results in Table 9

(7) table10_het.do -- allow gammas to depend on gender, age, strength of friendship; produces results in Table 10

(8) table11_recip.do -- allow gamms to depend on reciprocity of friendship; produces results in Table 11

(9) models.do -- programs for estimating bivariate order probit models with 2-way feedback, called by other do-files

(10) fig2a_fixrho.do -- estimate baseline model fixing rho at various levels (for figure 2)



Gauss files:

logits.zip contains Gauss program and output files that estimate bivariate ordered logit models
and produce the results in table 8 and figure 2b.
